Is the Earth Actually Cooling?
The world leaders who met at the United Nations to discuss climate change on Tuesday are faced with an intricate challenge: building momentum for an international climate treaty at a time when global temperatures have been relatively stable for a decade and may even drop in the next few years.Climate Progress points to this chart from the UK's weather service, known as the Met Office, to set things straight:
The chart shows a clear trend towards warming, even with the anomalous year of 1998. If you take a large enough data set—and the evidence for global warming encompasses lots of data—it should be easy to find two data points that buck the overall trend. That's just what the skeptics have done. But no one with any serious understanding of statistics (or thermodynamics) could possibly mistake the warming trend.
